ADA Ethereum

1. Here's a brief introction to several mainstream digital currencies to give you a rough idea. After that, I will talk about the specific currency from time to time

bitcoin is the originator of digital currency and the most valuable virtual currency. Because blackmail virus only takes bitcoin, it has entered the public view. The soaring price of bitcoin in 2017 has attracted a large number of investors to enter the digital money market. Because the number is small, it is only 21 million, which has a strong deflationary attribute
of course, I am extremely optimistic about the future of bitcoin. Of course, many people are not optimistic about digital currency. Here, it is most pertinent to quote Krugman's view:
"at least for now, buying bitcoin is still a good investment. But that doesn't mean the experiment was successful. The original intention of establishing a monetary system is not to make those who hold money rich, but to make transactions convenient and benefit the whole economy. And none of these bitcoins came to us. "
reborn currency
a protocol currency issued by reborn, which is the base currency of reborn network. It can circulate in the whole reborn network, with a total amount of 100 billion, and graally decreases with the increase of transactions. Reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system, Ripple labs (formerly known as opencoin) is the operating company of ripple coin
unlike bitcoin, reborn is a kind of transaction protocol, which is called smart contract in technical terms. It supports people to pay in any currency, and does not need a central data exchange center, so the transaction confirmation time of ripple is only 35 seconds, while that of bitcoin is 10-40 minutes

Ethereum
Ethereum is the name of currency used in Ethereum, which is used for payment calculation in Ethereum virtual machine. Ethereum is a blockchain that can be used to deploy decentralized applications. It is an open source computer platform and blockchain platform. At the end of 2013, it was founded by vitalik buterin, a Russian programmer
there is a key difference between the blockchain technologies used by Ethereum and bitcoin. Ethereum's data processing speed is faster than that of bitcoin, because once agreed, Ethereum's system will automatically apply to the terms and conditions in the contract
unlike bitcoin, the value of Ethereum depends on whether the applications on the platform of Ethereum are prosperous or not, just like the price of oil will rise with more machines using oil

bitcoin cash
bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block
strictly speaking, however, there are different opinions on whether this is a new branch of bitcoin or another kind of "counterfeit currency". But now the offer of bitcoin cash is nearly 20000 yuan, so it's not too much to use it as a kind of "Shanzhai coin" to divide bitcoin traffic

IDA coin, ADA in English, is a proct of Cardano project. The total amount of Aida is 4.5 billion yuan, and 3 billion yuan will participate in the subscription. Among them, 2.5 billion ADA will be used for platform subscription, 500 million for the financial support of the development company's operating company, and 1.5 billion ADA coins will continue to be issued in the form of block awards
Cardano is a project started in 2015 to change the way cryptocurrency is designed and developed. This project is aimed at technical reformers, technical improvements to bitcoin and existing platforms. If bitcoin, Ethereum and other projects have many other shortcomings, Cardano can solve them<

lightcoin
a currency based on bitcoin protocol, but it does not require very high computing power, and it can also be mined by ordinary computer. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
for a long time, there has been a voice that "lightcoin will replace bitcoin", which is impossible. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin<

stellar currency
stellar currency, a digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and legal tender. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
star is a diversified team. The board members include Keith rabois, former COO of square, Patrick collison, CEO of stripe, Jackson Palmer, co-founder of dogcoin, and naval Ravikant, co-founder of angellist, who will be the consultant of the project< New economy movement, or NEM, was founded on January 19, 2014. The founder is a mysterious person in bitcointalk.org forum called utopianfuture. The original intention of utopian future was to build a second-generation digital currency NXT. He then realized that NXT's distribution model was unreasonable, so he devoted himself to NEM with egalitarian distribution
as a kind of cryptocurrency, new coin does not need much computing resources to maintain the operation of nodes. The proof of importance (POI) engine of NEM reces the threshold of computing resources to participate in non-traditional blockchain<

dascoin
formerly known as black coin, is a kind of counterfeit currency of bitcoin, which focuses on anonymous function. There are many innovations, such as master node network, fast payment, mixed currency anonymous technology, proposals can vote, and developers have fixed budget support. The core consists of a unique incentive P2P network. Miners are rewarded for maintaining blockchain security; The main node holders are rewarded for verifying transactions, storing data and providing a variety of services
the feature of anonymity meets the needs of some investors for absolute privacy. Although bitcoin is also widely used in money laundering and other illegal transactions e to its anonymity, it is only "pseudo anonymity", and the transaction of bitcoin can still be traced back to the traders themselves.

2018! The 10th anniversary of Nakamoto's white paper! Opened a new world, 1994? What do you mean? God founded Ethereum in 2013. Zhao CHANGPENG, the founder of coin an, entered Hurun's first digital currency rich list with us $1.1-2 billion, ranking third in the world. Guan Jianshi, Zhao spent 160 days! There are many examples of ordinary Baishi making millions with one or two million in 2017! In 2017, currencies with a rise of less than 30 times are listed as substandard currencies! In 2018, almost all the big and medium sized Internet giants will enter the block chain. Even today, we believe that digital money is a tulip bubble friend (such as Buffett and Lang Xianping). Go home and write a review and burn it to me. If you want to make one or two hundred times in 2018, please pay attention to me, because I trust my dream to you, for fear that you will not receive enough mana

now let's talk about the promising digital currency in 2018:

< img SRC=“ //www.yuanxue365.com/en/img_9213b07eca806538cb8204909bdda144ac3482cd "/ >

1. Bitcoin: don't doubt that you can buy bitcoin at the current price. Of course, there are some ups and downs in a few days. From the end of 2017 to now, bitcoin has dropped by about 60%, which is just the opportunity to enter, Many people think that bitcoin is a proct of energy consumption without any value. I tell you, when bitcoin falls, almost all other currencies are falling, which indicates that bitcoin's price is the wind vane of other currencies. Bitcoin enters into futures trading and has a short mechanism. Then bitcoin plummets. The reason is that it is forbidden or supervised by a certain country, which is just like pulling a calf, We should not think that short selling is a bad thing. With a short selling mechanism, the real price of goods can be reflected, and the risk is relatively small. But if you want to earn dozens of times by buying bitcoin, it's possible, but now you'd better wash and sleep

Ethereum and the top 40 currencies: just one word: the average growth of these currencies will definitely exceed that of bitcoin

3. Currencies to be listed or not to be listed soon: if you want to make a hundred times profit in 2018, you must focus on those currencies to be listed or not to be listed soon. With the experience of 2017, the success rate is only 5% - 8%! Very low! But if you invest 10 kinds of money, one of them will increase 100 times, and the others will become rubbish, and the income will be 10 times of the investment! To improve the success rate is what you need to do. Say white point and find valuable currency. Don't believe that XX currency will circulate in the future. Facts have proved that if the total amount of digital currency is constant, human beings will inevitably enter the era of deflation. If the total amount of digital currency is not constant, almost all of them are enterprise currency and have no value! The currency, which was listed soon in 2018, is more optimistic about EOS because it has a great opportunity to get started after the price falls, and the domestic market is more optimistic than the original chain and gongxinbao. After reading the form below, don't feel sorry for those who didn't participate. There are plenty of opportunities in the future

we must make it clear that if we want to increase 100 times, it is definitely not the most famous and mainstream currencies, but those with huge development potential and the current currency price is far undervalued. Centennial is most likely to appear among the tokens with a unit price of 0.01-2 yuan. For the token that will be listed soon, dig out the background of this coin and invest in its value

in the end, if you want to earn 100 times in 2018, just pay attention to me! If you don't believe me, pay attention to me and witness together

5. With the upgrading of Ethereum to version 2.0 this year, the consensus mechanism will be converted to POS, which will have a huge impact on miners. There are two choices for miners. One is to sell mining equipment and buy eth to adapt to the stacking mechanism of POS; The second is to switch the miner to other networks supporting GPU miner. Nick foster, a representative of kabombacks, a US mining equipment distributor, said most eth miners would choose the latter

after Ethereum is upgraded to version 2.0 POS mechanism, miners may switch mining machines to other networks
as Ethereum is finally ready to start its Ethereum 2.0 upgrade later this year, thus eliminating the long-term delay, the network will start to move towards the proof of rights model

therefore, the network will give up the workload proof consensus algorithm, so that eth miners have little choice. As their equipment will become obsolete, they will be forced to start mining counterfeit coins or re qualify as eth mortgagors. So, what is the current situation of Ethereum mining? With the coming transition, what will happen to the whole instry< At present, Ethereum consensus is based on POW system, which is similar to bitcoin (BTC). As a result, Ethereum's mining process is almost the same, as miners use their computing resources to earn rewards for each block they try to complete< However, there are still major differences between these processes. Although bitcoin mining has relied almost entirely on ASIC (large, loud machines designed specifically for cryptocurrency mining, most of which are concentrated in areas with low electricity prices), Ethereum's pow hash algorithm ethash is designed to support global chip manufacturers (such as NVIDIA and AMD). As Thomas Heller, global business director of cryptocurrency mining pool f2pool, explained in a conversation with cointegraph, GPU is much cheaper and easier to access than ASIC

"as ASIC is a very professional machine, when a new generation of procts is released, it is usually a huge technological leap. As a result, they have a much higher hash rate and are more energy efficient than the previous generation. This means that those manufacturers have spent a lot of money to research and develop it. Their machines are usually very expensive, and GPUs are much cheaper. "

Heller added that those who use GPU miners "have more flexibility to mine." For example, the popular NVIDIA geforce GTX 1080 Ti card can mine more than 15 different currencies, while ASIC units usually support only one currency

nevertheless, Ethereum is not completely immune to ASIC miners - at least in its current state. In April 2018, bitcontinent released antminer E3, an ASIC specially proced for mining Ethereum. Although widely praised for its hash rate of 180 megahashes per second and power consumption of 800 watts, it has received different responses from the Ethereum community. After the ASIC is inserted, a considerable number of GPU rig owners seem to suffer from loss of profits, and some are even forced to switch to other networks

"in the white paper, ETH must have ASIC resistance. I would like to say that the white paper stands for something "is one of the highest comments on the AR / ethermining topic about the topic discussed when antminer E3 was announced. Another reddit user argued that "the $800 only applies to 180mh."“ Split or die of a nation. "

some Ethereum users continue to suggest that bitmain's mining devices can lead to greater concentration, thus increasing the possibility of attack by 51%. Soon, a group of developers put forward "programmed workload proof" or progpow, which is an extension of the current Ethereum algorithm ethash, aiming to make GPU more competitive and promote decentralization

according to a paper published in March by Kristy Leigh Minehan, co-founder of progpow, about 40% of the hash rate of Ethereum is generated by bitmain ASIC. Alejandro de la Torre, the vice president of poolin, is the sixth largest pool of eth. He confirmed to cointegration that "GPU mining is still dominant" in Ethereum network, and added:

"at present, the profit of eth mining is not high, and the management threshold and cost of GPU equipment are higher than ASIC equipment. Compared with ASIC devices, GPU devices are more flexible, and you can use other algorithms to switch to other coins. "

progpow has not been integrated into Ethereum, and it is not clear when it will be finally implemented - in March, Ethereum core developers were debating whether progpow will really benefit the network in nearly two hours, and failed to reach a consensus. It is worth noting that a bitmain representative has previously told cointegraph that the mining hardware giant does not intend to extend the service life of antminer E3 to start operation after October 2020: "as far as we know, mining will end in October or some time after that."

a safe but uncertain future

indeed, Ethereum will stay away from mining in the future. Ethereum 2.0, which is planned to be launched later in 2020, is a major network upgrade on the blockchain, aiming to transfer its current POW consensus algorithm to a virtual POS (known as "block verifier")

more specifically, users are randomly selected considering their wealth in the network or their "interests". In other words, the more coins a POS verifier chooses to put in, the more coins accumulated as a reward

according to vitalik buterin, the co-founder of Ethereum, e to the transition, the network will be more secure and the attack cost will be higher than the network of bitcoin, although the debate about the better consensus algorithm in the encryption community has lasted for many years. However, it is not clear when to start Ethereum 2.0, as many errors and management issues are reported to be delaying the process

another hypothetical benefit of POS system is that it has higher energy efficiency than pow blockchain. According to digiconomist, the cryptocurrency's total annual footprint is 59.31 terawatts per hour, which is comparable to the electricity consumption of Greece as a whole. However, since a report in July 2019 estimated that 74% of the exploitation of bitcoin was done using renewable energy, the environmental impact of bitcoin does not seem to be so serious

what will happen to the actual Ethereum miner? According to the documentation of Casper upgrade as part of Ethereum 2.0 roadmap, the network will initially support a hybrid model including both POW and POS, thus providing some space for block verifiers and GPU / ASIC miners. Jack O & 39, CEO of skale network; "There will definitely be a transition period when two networks are running at the same time," Holleran told cointegration The CEO of scale network (based on Ethereum's blockchain platform) gave a detailed description of this process:

"the transition from eth1 to eth2 takes time of course - it may be years rather than months. The good news about this slow transition is that dapps and defi platforms will be able to roam around based on survivability, security and real-world evidence of adoption. This is a positive impact on the Ethereum ecosystem. "

dig or not

once Ethereum is fully in the POS orbit, miners will have two options. One is to sell the equipment and use the money to accumulate more Eth and start mortgage. The other is the choice for GPU miners, which is simply switching to other ethash networks and mining counterfeit money. Nick foster, a representative of kabombacks, a US mining equipment dealer, told cointegration that most eth miners would choose the latter:

"what I want to say is that most of the miners have not really entered Ethereum or the mining of specific tokens. Yes, there is a certain amount of mineral deposits and holds, but I oppose the view that a large number of Shanzhai coin miners hold their coins at any time. "<

foster then described how he used 3gb GPU units to mine ethash's point-to-point blockchain asset ravencoin (RVN). Once it was unable to mine eth, he said, "this is the reason for mining crows. I immediately sold stability to BTC, and then sold it to US dollars to pay for my rights. I would say that a lot of people are adopting this strategy. "

as foster concludes, he wants eth miners to jump out of the network, and new players - those who don't invest in power infrastructure or drilling rigs - will take a stake in eth. He described the following:

"I can't imagine if I found a five-year lease with $0.04 of electricity and I was mining eth, I decided to sell everything and then continue to pay the rent so that I could hold eth as a share. Substitute. "

Marc fresa, founder of asic.to, a mining firmware company, agreed in a conversation with cointegraph: "if you invest in mining, you won't bet because you have enough room to grow."

one of the main counterfeit coins that may benefit from POW miners leaving Ethereum is Ethereum classic (etc), which is a more conservative version of the blockchain. It is reported that there is no POS related plan. As it also runs on the ethash algorithm, the startup of Ethereum 2.0 may lead to the migration of miners, so its hash rate may have a significant peak

eth's larger pools have similar options. When asked about the company's plans for Ethereum after pow, Heller told cointegraph that after the announcement of Ethereum's POS upgrade, f2pool launched a sister company called story.fish in early 2018. Story.fish has started to provide mortgage services for other POS and delegated POS projects, such as tezos (xtz), Cosmos (atom) and Cardano (ADA), e to numerous handover delays. For prin, e to the transition to POS, it "may temporarily give up supporting eth mining," de la Torre told cointegraph

other top eth pools, namely nanopool, ethermine, pool center, sparkpool and spiderpool, did not respond to requests for comment from cointegraph.

6. First of all, what ADA does is the concept of smart contract. I think you should be familiar with smart contract, but for some new people, I still want to explain. The so-called smart contract is to write a contract that the computer can understand through the programming language, because there is no need for a third party, and the executor of the contract is a selfless computer, so it solves the problem of trust between people. For details, please refer to GitHub smart contract
Ethereum is a blockchain smart contract. Now Ethereum ranks 2-3 in the market value ranking, with a market value of 25% of bitcoin. However, Ethereum also has some problems, such as slow trading, high fuel costs and the mining mechanism that has been criticized repeatedly. Familiar? All of bitcoin's problems are with Ethereum. Some time ago, the Ethereum cloud cat game developed on Ethereum went online in the first week, directly blocking Ethereum's trading network. I tried to pay a high gas fee of nearly 100 yuan, but I still couldn't transfer it successfully. This can't help but lower my expectation of Ethereum. Ethereum is a great idea of V God, but after all, it is a pioneer, and there is a long way to go from perfection.

7. If you buy, you can go directly to the exchange. But if you ask about the investment method, it will be difficult to learn for a while. It is suggested to take a look at the recent market of bitcoin, and password finance can see the recent market and analysis.

8. Miner is composed of high-end graphics card, a miner to use a lot of high-end graphics card composition. There are a lot of loaders, so the price of graphics card will rise naturally. It's all taken to the loader.

9. Bitcoin, Ethereum, ecell and Ida are my favorite. I have some of them in my hand. I hold them separately and don't put eggs in the same basket.

10. Hello
ADA, a project that started in 2015, has been attracting much attention. According to its LinkedIn data, its founder Charles hoskinson served as co-founder and acting CEO of bitstock from July 2013 to October 2013, and later served as CEO of Ethereum from December 2013 to may 2014
before starting the ADA project, he was the co-founder of bitstock and Ethereum. He had entrepreneurial experience with BM and V God. His resume and entrepreneurial background belong to zhendaniu
in Charles's view, he thinks that the first generation of cryptocurrency is bitcoin, and the problem bitcoin should solve is that when two people trade, they need to verify with a centralized organization. But the problem is that the transaction is never as simple as transferring money from one person to another. There is often a condition behind it
for example, a person may ask another person to do something for him, and then he will pay a sum of money to this person, which involves a contract, so Ethereum, the second generation cryptocurrency, appears
Ethereum introces Turing complete programming language into the blockchain, so that we can realize the contracts we need to do through the programming language, which is what we often call smart contracts
bitcoin and Ethereum are currently limited by TPS, network bandwidth and data volume, and their scale-up process is blocked. When Charles started the ADA project, he said that he hoped to change the design and development mode of cryptocurrency to make it have a more reasonable and secure user experience.
